ADS-B LNA High Performance Triple Filter Low NF Amplifier by RTL-SDR Blog

hi man drop strong and welcome to the back office teardown lab recently i was trying to use my sdr to pick up some weather satellites and unfortunately although it was working it wasn't very clear because there was a lot of noise and despite turning up the gains on the sdr uh software it really didn't make a bit of difference so i obtained this it was a good price it was about fiverr and this is a low noise amplifier and before i rip the package is there anything useful on it it says it's an spf 5189 and there are a variety of these and they come in a variety of flavors and strengths and all of this i believe this one is supposedly to give you a 0.6 decibel gain and it has the range 50 to 4 000 megahertz it looks like we're gonna have to zoom right in today to get any chance of seeing that you can see it right there the spf 5189z and the frequency is 4 524gb 15 megs to 4 gigahertz at 5
